Version 1.2.0-rc.2 introduced an ineffective privilege drop when requesting container network setup, therefore subsequent functions are called with root privileges, the attack surface is rather limited for users but an attacker could possibly craft a starter config to delete any directory on the host filesystems. A security fix has been included in Apptainer 1.2.1. There is no known workaround outside of upgrading to Apptainer 1.2.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":3.3},"cwes":["CWE-269","CWE-271"],"references":["https://github.com/apptainer/apptainer/pull/1523","https://github.com/apptainer/apptainer/pull/1578","https://github.com/apptainer/apptainer/security/advisories/GHSA-mmx5-32m4-wxvx","https://github.com/apptainer/apptainer/pull/1523","https://github.com/apptainer/apptainer/pull/1578"],"products":["lfprojects:apptainer"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-38496","score":0.0026,"percentile":0.17796,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-mmx5-32m4-wxvx","url":"https://osv.dev/vulnerability/GHSA-mmx5-32m4-wxvx","summary":"Ineffective privileges drop when requesting container network","modified":"2026-09-10T03:49:42.498530978Z","packages":[{"ecosystem":"Go","name":"github.com/apptainer/apptainer","purl":"pkg:golang/github.com/apptainer/apptainer","ranges":[">=1.2.0 <1.2.1"],"fixed":["1.2.1"]}]},{"id":"GO-2023-1965","url":"https://osv.dev/vulnerability/GO-2023-1965","summary":"Ineffective privileges drop when requesting container network in github.com/apptainer/apptainer","modified":"2026-03-03T04:54:05.601435Z","packages":[{"ecosystem":"Go","name":"github.com/apptainer/apptainer","purl":"pkg:golang/github.com/apptainer/apptainer","ranges":[">=1.2.0 <1.2.1"],"fixed":["1.2.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
